Fine Definition of IR Spectra from High Temperature Interactions of U + O2.
Abstract
The basic objective was to obtain the mid-infrared spectra of ionized species resulting from the interaction of U + O2. The peaks observed in the 770-900/cm region resulting from the codeposition of UO2 and UO with NO2 in Ar matrices previously have not been reported. Normal coordinate calculations show that the observed frequencies may be attributed to a species containing one uranium atom and two oxygen atoms which is either completely isolated or loosely complexed. Although neutral complexes are known to exist when metal halides are deposited in argon matrices doped with small molecules, the presence of two peaks at 1,244 and 1,182/cm, where NO 2(-) charge-transfer bands occur, suggest that the observed bands might be attributed to free UO 2(+) or UO 2(+) charge-transfer complexes with NO 2(-). The results suggest that matrix-isolation spectroscopy may be used to study the infrared spectra of cations or cation-complexes.
